How many years of continuous vacancy must occur for an easement to be presumed abandoned in Hawaii?

In Hawaii, there is no specific duration of vacancy that automatically leads to the presumption of abandonment for an easement. This means that the correct response is that there is no standardized period, which aligns with the answer choice stating "None of these."

The concept of easement abandonment can be complex and often involves considerations of intent and use. Abandonment is not solely determined by the passage of time but also by the actions or inactions of the easement holder. Thus, without a clear statutory requirement indicating a specific number of years, the presumption of abandonment cannot be established based on vacancy alone. This principle reflects the legal understanding that an easement may be retained even if not actively used for an extended period, unless there is evidence showing a clear intention to abandon it.
